I have to mostly agree with TL on this one Skunk (cough cough splutter

). The other presidents were lucky to avoid this and Bush was not as fortunate.
I support the opinion that is coming through from Clarke and O'Neill that Bush was obsessed with completing Daddy's War and that this took much of his focus, but in regard to the twin towers you can't pin that on the unfortunate schmo who happened to be in office at the time.
Mind you, I am betting the repugs would have gone just as hard after Slick Willie if it had happened on his watch, and that some (not all) of the repug debaters on this thread would be arging different and more aggressive approaches in that case.
